AUTOMATIC OIL-FEED FOR MOTOR-CARS.

Specification of Letters Patent.

Application filed December 11, 1914. Serial No. 876.744.

W lie it known that we, tiounotx' (undies lit-inn"; Snolroiiin-i; "and llim. Kixoimn. subjects of the Ring of (heat lliitaiih residing at 'limar u. Yew Zealand. have invented a new and useful Automatic (lil-l' eed 'lor )lotoriars; and we do hereby declare the 'l'ollowingz to be a lull. clear. and exact description f the same.

This invention relates ,to an automatic .ontrol l'or governing; the supply of lubricating: oil to the oil sumps of motor car engines and by means of which the oil supply to such sump is automatically maintained at a constant level.

The invention consists in arranging a float chamber about the same level as the oil sump and connecting the bottom of such chamber with the bottom oi the oil sump llllflllflll. a constantly open connection. 'llie upper end of the chamber is connected with the oil reservoir through a pipe having a valve seat opening that is adapled to he closed by a uwdle valve attached to a lie-at arranged within the. chamber when such The level of oil within the chamber will correspond with that of the. oil in the oil vsump ol' the eull'iue and the lloat and needle valve are so iltllllhltll as to cause the valve to be closed and the supply of oil shut oil when the level of oil in the sump is at the required height. .\s it falls below such height the lloat will fall and allow tresh quantities to tlow into the lloat chamber from the reservoir. An air vent is provided in the top of the lloat chamber to insure ot the free. flowing oi the oil therefrom.

'l'he. acoonmanyinfi drawing: is a sectional elevation ol the. feeder and showing its arrangement with respect to the engine oil sump which latter indicated in diagram.

t is the float chan'iber that is made of suitahle material and. of any desired capacity. .l upper end is closed by the screw cover 1 in order to allow of ilsinspection and cleansing whenever required. At its lower end it is formed with a female threaded socket piece. .1 that screws over one end of the, pipe connection l and which pipe connection leads into the bottom of tlq. engine sump E. The level of the chamber it may thus be adjusted in relation to the, oil sump E by screwing: the socket piece up or down on this pipe, and it is l'lfllfil'lll the desired position ."i s i anew,

float rises.

by means of the lock nut F screwed upon the pipe end beneath it.

"Any desired number of oil outlets a lead from the bottom of the chamber A into the socket piece C so that the oil flowing therefrom may pass into the pipe I and along it to the engine sump.

(i is the pipe leading from the oil reservoir and this pipe is connected by the union with a nipple titling l-l. upon the chamber cover 13. The passage through this nipple lilting is formed at its inner end as a needle valve seat J opening into a guide bore K in the cover.

A central guide stem M. projects upward trom the bottom of the chamber A and on it the lloat N is mounted so as to be free to rise and tall. The stem is provided with a stop on at a point a distance from its bottom, on which the float will rest when it is in the lowered position and thereby be prevented from closing thev outlets (I. To the top of the float is fixed the needle valve 0 which passes loosely into the bore K of the chamber cover and is adapted to fit into the valve seat 3 and seal the opening when the float is raised.

l is the air vent tube passing into the top of the chamber A and preferably bent over at its top to prevent the entry of dirt or the like.

In operation the oil level in the chamber A will be. the same as that required in the oil sump and the chamber is so adjusted in its height that. when the oil is at such level, the lloat will be raised to close the needle valve. As the oil in the engine sump is used up and the level falls there is a corresponding fall in the chamber A so that the float will drop and remove the needle valve from its seat and thereby allow enough oil to flow in from the reservoir to restorev the oil level to its original state. The level of the oil in the. engine sump is therefore automatically maintained.

What we do claim as our invention, and desire to secure by Letters Patent is 2- An automatic oil feed for motor cars having engine oil sumps, consisting of an oil chamber, a pipe connection leading from the bottom of .such chamber into the bottom of the engine oil sump, means for adjusting the height of the oil chamber in relation to such sump, an oil supply pipcdeading into.
